mubu:
– added possibility to define @track attribute in writeall message, allowing to save a given track over all the buffers in a .mubu file;
– added possibility to reload this file appending his content to the buffers of a given container.
– added attribute “externalfiles” allowing to save in mubu files, just the file name of loaded sound files. In this case sound files will be loaded directly from original files (if found in filepath) when mubu file is imported
– readtrackappend on empty track behaves as readtrack
– fixed crash importing not supported sound file format (e.g. m4a format)
